Navy SEAL Author of Osama Raid Book Did Not Violate Non-Disclosure Agreements: Lawyer

Johnson's letter also warned "further public dissemination of your book will aggravate your breach and violation of your agreements." Little did not identify what potential actions the Defense Department is considering and would not say if there are plans to halt the book's scheduled release next Tuesday.

Little said the "onus" was on the author to take unspecified action and that the letter "was not meant to be any kind of intimidation."

Though the former SEAL said he will donate a majority of the book's profits to charities that help the families of fallen SEALs, Johnson's letter suggested that all of the book's royalties belong to the U.S. government.

According to Johnson, in signing the non-disclosure agreements the SEAL acknowledged he "assigned to the U.S. government ... all royalties, remunerations, and emoluments that have resulted, will result or may result from a disclosure, publication or revelation of classified information not consistent with the terms of this agreement."
